Like millions of Americans, West Nyack’s Robin Bell dreads her commute. It’s not the time it takes to cover the 26,000 mile round trip. And while she certainly misses her family during the weeks she spends at her remote workspace; that is not the worst part. It’s the carbon footprint from the passenger and ski-equipped cargo planes that troubles her the most. Robin Bell is a climate scientist and air travel is the only practical way for her to get to her “office” at Field Camp Twin Otter in Antarctica.
Dr. Bell is currently the Senior Research Professor at the Lamont-Doherty Earth Observatory of Columbia University in Palisades, NY. She has just become the president-elect of the American Geophysical Union AGU, an internationally influential Earth and space science organization. In a transition process that mirrors the glacial pace of some geophysical systems, Bell will serve as president-elect for two years. She becomes president in 2019, the year the AGU celebrates its 100th anniversary. The president serves as the scientific leader of the organization and its public spokesperson.
Bell is currently one of the world’s leading experts in polar science. She directs research programs in Antarctica and Greenland; leads research on ice sheets, plate tectonics, and rivers; and leads the development of technology to monitor our changing planet. As chair of the National Academy of Sciences Polar Research Board, she was instrumental in launching International Polar Year 2007-2008, a major multinational push to study the polar regions.
Her interests range from ice sheet dynamics to sub-glacial ecosystems. Bell studies the mechanisms of ice sheet collapse and the environments beneath the Antarctic ice sheet, including the Gamburtsev Mountains. The Gamburtsev range, also known as the ghost mountains, are as large as the Alps with a summit that never sees the sun, buried beneath 2,000 feet of snow and ice.
“I use physics to paint pictures of the world,“ Bell said in a 2011 interview. “I’ve been incredibly lucky in terms of being able to leverage physics to see through to these places that are pretty much hidden to the human eye.”
Bell uses geophysics to observe “how the ice sheets work, how they grow, how they change and how they are changing now.” The model for how ice sheets behave was, until recently, as simple as “putting an ice cube on a table and letting it melt.’” Bell and her multinational scientific partners in Antarctica are observing a much more dramatic process. “Parts of the ice sheet…are like giant conveyor belts that move a lot of ice into the ocean fast. Conveyor belts that are as wide as the state of Rhode Island. “
As remote as her polar offices might be from our northern hemisphere Atlantic coastal setting, we are connected by the world’s oceans to the changes in the ecology of Antarctica and Greenland. In Antarctica, Bell is recording “how ice gets taken from the middle of ice sheets down along these fast flowing ice streams down into the ocean where they turn into icebergs and are the mechanism that raises global sea levels.”
“Since my grandmother was born, sea levels have risen one foot.” Bell said. “In the worst case scenario, the oceans could rise another foot in the next three decades, which means adapting to what we had seen since my grandmother was born a little quicker.”
Bell takes to the seas as a sailor as well as a scientist. “We sail as a family to soak in the open sea and sky and see new places together. I take a microscope and a small plankton net to look at the creatures in the sea, but that is just for fun.”
One of Bell’s recent projects included testing a new imaging system “icepod” that is designed to measure ice thickness and how much snow has fallen in the last 100 years and the temperature. Her commute north is shorter than her southern sojourn, just 2,000 miles to the town of Kangerlussag and another 3,000 to the spot where they measure the ice.
Here are a few things that Bell thinks people who live on the banks of the Hudson should keep in mind when contemplating the impact of global weather systems:
Integrate your concern for the environment into your life whatever it is… art, journalism, business… we have to embrace change and move away from a lifestyle based on carbon fuels.
Encourage kids to study science and engineering…. we need more really smart people working on the planet as a system if we want to keep it as a habitable place.
When you are standing in Memorial Park, Bell has a simple way to fathom the elevated height of the river. “Put your hand just below your knee…. the water has gone up that far since 1900.” Bell hopes that local governments will be mindful of this accelerating trend and place critical infrastructure above storm surge levels.
Even though she already gives to the fight against global climate change at the office, Bell’s activities extend beyond the traditional scope of scientific research. Bell was the director of the ADVANCE program at Columbia’s Earth Institute from 2004-2011 that increased the participation and advancement of women scientists and engineers at the University. She was also instrumental in the development of the International Polar Year 2007-8.
Most of us are as likely to walk on the moon, as we are to step onto the ice at the South Pole. But what happens underneath Antarctica’s frozen surface shapes our future. Which is why we are fortunate that one of our neighbors is willing to make the trip for us. Let’s just hope that policy makers have the wisdom to comprehend the implications of her findings and the integrity to take corrective action.
